(A) The plan must evaluate cost effectiveness, equity, technological feasibility, benefits to the grid, and benefits to customers of marginal cost-based rates for each customer class.

(B) If after consideration of the factors in Subsection 1623.1(a)(1)(A) the plan does not propose development of marginal cost-based rates, the plan shall propose programs that enable automated response to marginal cost signal(s) for each customer class and evaluate them based on their cost-effectiveness, equity, technological feasibility, benefits to the grid, and benefits to customers.

(C) The Large POU or the Large CCA shall review the plan at least once every three years after the plan is adopted. The Large POU or Large CCA shall submit a plan update to its rate approving body where there is a material change to the factors considered pursuant to Subsections 1623.1 (a)(1)(A) and (B).

(A) that despite a Large POU's or Large CCA's good faith efforts to comply, requiring timely compliance with the requirements of this article would result in extreme hardship to the Large POU or the Large CCA,

(B) requiring timely compliance with the requirements of this article would result in reduced system reliability (e.g., equity or safety) or efficiency,

(C) requiring timely compliance with the requirements of this article would not be technologically feasible or cost-effective for the Large POU to implement, or

(D) that despite the Large POU's or the Large CCA's good faith efforts to implement its load management standard plan, the plan must be modified to provide a more technologically feasible, equitable, safe or cost-effective way to achieve the requirements of this article or the plan's goals.

(A) Within thirty (30) days after adoption of a plan or material plan revision pursuant to this subdivision, each large POU and Large CCA shall submit its plan to comply with the requirements of this Section 1623.1 or material plan revision to the Executive Director.

(B) The Executive Director shall review plans or material plan revisions and either return them to the Large POU or the Large CCA for changes or submit them to the Commission for review and potential approval. The Executive Director shall make an initial determination whether the plan or material plan revision is consistent with the requirements of Section 1623.1(a)(1) and (2). In reviewing plans and material plan revisions, the Executive Director may request additional information or recommend changes to make it consistent with the requirements of Section 1623.1(a) (1) and (2). The Large POU or Large CCA shall respond to requests or recommendations within ninety (90) days of receipt from the Executive Director. The Executive Director shall then submit the plan or material plan revision to the Commission with a recommendation on whether to approve it. The Commission may also request additional information and shall approve plans and material plan revisions which are consistent with Section 1623.1(a)(1) and (2), and which show a good faith effort to meet the goals listed in Section 1623.1(a)(1) and (2). The Commission may place conditions on its approval of plans or material plan revisions that are necessary to guarantee that the plan or material plan revision will comply with Section 1623.1 (a)(1) and (2) by a date certain.

(C) Each Large POU and Large CCA shall submit to the Executive Director annual reports demonstrating their implementation of plans approved pursuant to this subsection, as such plans may be revised pursuant to this subsection. The reports shall be submitted one year after plans are approved pursuant to subsection (2) and annually thereafter.

(A) Large POUs and Large CCAs shall apply for approval of marginal cost-based rates only for those customer classes for which the rate-approving body determines such a rate will materially reduce peak load.

(B) Large POUs and Large CCAs shall provide the Commission with informational copies of tariff applications when they are submitted to their rate-approving bodies.

(A) The portfolio of identified programs shall provide at least one option for automating response to MIDAS signals for each customer class that the rate-approving body determines such a program will materially reduce peak load.

(B) The programs shall allow customers to respond to MIDAS signals indicating marginal cost-based rates, marginal prices, hourly or sub-hourly marginal greenhouse gas emissions, or other Commission-approved marginal signal(s).
